** plz**which statement best compares a trace fossil to a fossil that forms as a result of an entire organism being trapped in amber?

both show the exact structure of the organism.
both require that the hard parts of the organism dissolve.
both form as a result of the organism leaving imprints in sediment.
both can possibly be used to study the organism's size.

Both form as a result of the organism leaving imprints in sediment.

A fossil is a remain of plant or animal material which were once alive. A fossil is formed when a dead organism being treated by microorganism present in the soil. The soft tissues are easily decomposed by the microorganism, but the hard tissues like bones, shells, and wooden parts of plants remains are left. These remains are covered by the layers of sediments. These sediments becomes compact mass or rock. The rock bearing the dead remains of plants and animals is called as fossilized rock.  

A trace fossil and a fossil being formed as a result of an entire organism being trapped in amber both forms as a result of the organism leaving imprints in sediment because whether it is a trace or remain of an organism or an entire body of organism, the pile of layers of sediment will exhibit the skeletal features of the organism as an imprint in the form of rock after compaction. It can facilitate the identification of the organism.  

the answer is a or when it says crossing over

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
